Happy Pi Day - No Logo from Google?

Today is Pi Day, yes, March 14th, 3.14 and due to π being about equal to 3.14 (i.e. 3.1415926). Pi is a favored number by mathematicians and tech people - so I am a bit surprised there is no mention of it via a Google logo or Ask theme. However, I don't think they did anything in the years before.

But that didn't stop us, as you can see, we have our Pi Day theme live here. Here is a picture for archiving purposes.
